Callum Haas · Answer 1

Answer: Its pH is around 6.5

Explanation:

The pH of the blood is not acidic in nature. It is slightly alkaline with a pH of around 7.35 to 7.45. This shows that the the blood is slightly alkaline in nature.

There is a mechanism called homeostasis by which the pH of the blood is regulated.

In case of any disease the pH of the blood changes and it can be controlled by medications. As a part of regular check ups the doctor checks the pH of the blood.

Armani Williams · Answer 2

Its pH is about 6.5.

Explanation:

The pH of any fluid is measured by the hydrogen ion concentration. A pH of 7 is neutral, pH of below 7 is acidic, and above 7 is basic in nature.

The variety of factors such as lung function, kidney function, endocrine function, vomiting, diarrhea, and urinary tract infection affects the pH of the blood. So, the normal blood pH is slightly alkaline in nature and regulated between 7.35-7.45.
